Question

the length of a rectangle is 30 cm and its perimeter is equal to the perimeter of a square with side 24 cm find the breadth and the area of the rectangle​

Answer 1

Answer:

540

Step-by-step explanation:

Given :-

Length of rectangle = 30 cm

Side of square = 24 cm

Perimeter of Square = 4a

P = 4 x 24

P = 96 cm

Now, As given in the question that perimeter of square is equal to rectangle.

Perimeter of rectangle = 96 cm

2(l+b) = 96

30 + b = 96/2

b = 48 - 30

b = 18 cm

Now,

Ar(rectangle) = l × b

Ar(rectangle) = 30 x 18 cm²

Ar(rectangle) = 540 cm²

Answer 2

Answer:length = 30cm

2(l+b) =. side ×4

l+b = 2side

30 + b = 2 ×24

b = 48- 30

b= 18cm

area = lb

540 cm square
